Swing中的JTable中添加Checkbox不能选中

场景：Swing中的JTable中添加Checkbox不能选中,该如何处理

Swing中的JTable中添加Checkbox不能选中
JTable中的一列我渲染成了CheckBox，但是当鼠标点击后，不能显示出选中的状态。请高手帮忙解决一下啊。在线等！
JTable的model:

class EntitySynchroTableModel extends AbstractTableModel{
  private List<Boolean> checkBoxValues = new ArrayList<Boolean>();
  private List<ComparisonResultVO> datas;
  private List<ComparisonResultVO> selectdatas;
   
  public EntitySynchroTableModel(){
  datas = new ArrayList<ComparisonResultVO>();
  selectdatas = new ArrayList<ComparisonResultVO>();
  }
   
  public int getRowCount() {
  return datas == null ? 0 : datas.size();
  }

  public int getColumnCount() {
  return columns == null ? 0 : columns.length;
  }

  public Object getValueAt(int rowIndex, int columnIndex) {
  if(null==datas || rowIndex>datas.size()-1)
  return null;
  ComparisonResultVO tempVO = datas.get(rowIndex);
  if(getColumnName(columnIndex).equals(CHOOSE)){
  return this.checkBoxValues.get(rowIndex);
  }
  if(getColumnName(columnIndex).equals(CURNET_RESOURCE)){
  return tempVO.getLocalEntity();
  }
  if(getColumnName(columnIndex).equals(NOTE)){
  return tempVO.getNote();
  }
   
  for(Map.Entry<LocalNetVO,RemoteEntityStatusVO> entity : tempVO.getRemoteEntityMap().entrySet()){
  if(getColumnName(columnIndex).equals(entity.getKey().getFromNetlName())){
  return entity.getValue();
  }
  }
  return null;
  }
   
  public Class<?> getColumnClass(int columnIndex){
  if(getColumnName(columnIndex).equals(CHOOSE)){
  return Boolean.class;
  }
  if(getColumnName(columnIndex).equals(CURNET_RESOURCE))
  return BaseVO.class;
  for(LocalNetVO vo : localNetVOs){
  if(getColumnName(columnIndex).equals(vo.getFromNetlName()))
  return RemoteEntityStatusVO.class;
  }
  if(getColumnName(columnIndex).equals(NOTE)){
  return String.class;
  }
  return null;
  }
   
  public String getColumnName(int column){
  return columns == null ? "" : columns[column];
  }
   
  public void clear(){
  if(null != datas){
  datas.clear();
  fireTableDataChanged();
  }
  }
   
  public void setData(List<ComparisonResultVO> datas){
  this.datas = datas;
  this.checkBoxValues.clear();
  for(ComparisonResultVO result : datas){
  this.checkBoxValues.add(false);
  }
  fireTableDataChanged();
  }
   
  public void removeRow(int rowIndex){
  if(null != datas){
  datas.remove(rowIndex);
  fireTableDataChanged();
  }
  }
   
  public int getColumnIndexByName(String columnName){
  for(int i = 0 ; i < columns.length ; i++){
  if (columnName.equals(columns[i])){
  return i;
  }
  }
  return -1;
  }
   
  @Override
  public boolean isCellEditable(int rowIndex, int columnIndex) {
  if(this.getColumnName(columnIndex).equals(CHOOSE)){
  return true;
  }
  return false;
  }
  }

CheckBoxRenderer及Editor：

class CheckBoxRender extends JCheckBox implements TableCellRenderer {
  public CheckBoxRender(){
  super();
  }
  public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
  JCheckBox box = new JCheckBox();
  box.setHorizontalAlignment(JLabel.CENTER);
  box.setSelected(Boolean.TRUE.equals(value)); 
  return box;
  }
  }
   
  class CheckBoxEditor extends DefaultCellEditor {
  public CheckBoxEditor() {
  this(new JCheckBox());
  }
   
  public CheckBoxEditor(JCheckBox checkBox) {
  super(checkBox);
  checkBox.setHorizontalAlignment(JLabel.CENTER);
  }
  }

Java code

    public class MyComboBoxRenderer extends JCheckBox implements TableCellRenderer {

        public MyComboBoxRenderer() {
            super();
        }
        public Component getTableCellRendererComponent(JTable table, Object value,
                boolean isSelected, boolean hasFocus, int row, int column) {
            if (isSelected) {
                setForeground(table.getSelectionForeground());
                super.setBackground(table.getSelectionBackground());
            } else {
                setForeground(table.getForeground());
                setBackground(table.getBackground());
            }
            this.setSelected((Boolean)value);
            return this;
        }
    }

    public class MyComboBoxEditor extends DefaultCellEditor {
        public MyComboBoxEditor() {
            super(new JCheckBox());
        }
    }
